Flow chart runs only once ?

Newly I realized the flow chart in the state1 is excuted only one time at state entry. Actually I expected the cnt shall be counted up every loop as long as the state1 is active.
How can I fix it so that the flow chart is called every loop?
I found also the following note. It would mean the observed behavior is intended?
If a Stateflow chart contains only a flow chart, the chart evaluates the flow chart each time the chart wakes up. In contrast, the chart evaluates any flow chart inside a state only during state entry.

Hi Xiaohong,
When you connect a Stateflow 'default transition' to a flow chart, it is designed to execute only upon entry into the state.
Please refer to the ‘Workflow for Stateflow Chart Execution’ section of the following documentation.
Below is a model similar to the model provide by you, where we can observe that the variable ‘cnt’ is updated only once.
To update the variable ‘cnt’ with each iteration, connect the junction to the Stateflow state ‘State1’ as illustrated in the following figure.
Hope this helps.
